The Capri Blue Grotto, or Grotta Azzurra in Italian, is a stunning sea cave known for its mystical blue waters. This effect is caused by sunlight filtering through a submerged cavity, making the water glow from below.

Reaching the cave is an adventure. The entrance is small, about a meter high and two meters wide. Visitors must lie flat in small rowboats, guided by local experts. The grotto is only accessible during calm seas and low tides, adding to its exclusivity.

Despite these challenges, the Capri Blue Grotto remains a popular tourist attraction. It is near Capri’s Marina Grande and can be reached by boat tours from various points around the island.

Dr. Alessandro Rossi, a marine geologist, says, “The Blue Grotto’s unique lighting conditions make it a natural wonder, with few other locations in the world offering such a vivid underwater spectacle.” Tour guide Giovanni Esposito adds, “Navigating the small entrance is part of the adventure, and the breathtaking sight inside makes it all worthwhile.”

This dazzling cave, with its ethereal blue water, continues to captivate visitors from around the world.
